CLASP-BUCKLE.

Specification of Letters Patent.

Patented Mar. 30, 1915.

Application filed March 6, 1912. Serial No. 681,872.

To all whom it may concern:

Be it known that 1, WILLIAM P. BARTEL, a citizen of the United States, residing at l/Valtham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Clasp-Buckles, of which the following is a specification.

This invention relates to a clasp buckle, the object of the invention being to provide a clasp buckle adapted to be used in connec tion with overshoes, coats and other articles of apparel in which two members are formed to interlock one with the other and a spring is fastened to one of said members at one end thereof, the free end. of said spring engaging the other of said members and holding said two members in interlocking engagement.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out'in the claim thereof.

Referring to the drawings:' Figure 1 is a plan view of a clasp buckle made in ac cordance with my invention and adapted to be used in connection with overshoes. Fig. 2 is a sectional elevation taken on line 22 of Fig. 1. Fig. 3 is a transverse section taken on line 3-3 of Fig. 1. Fig. 4 is a plan view of a modified form of my improved clasp buckle such as is adapted to be used with heavy coats. Fig. 5 is a sectional elevation taken on line 55 of Fig. 4.

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, referring to Figs. 1 to 3 inclusive 10 is one of the interlocking members of the buckle and 11 is the other interlocking member. The members 10 and 11 are formed of sheet metal struck up into the shape shown in the drawings. The member 10 is provided with a slot 12 at one end thereof adapted to receive a strap or other fastening means by which it may be attached to a shoe. Said member 10 is further provided with slots or orifices 13, 13.

The interlocking member 11 is formed of sheet metal and has two downwardly extending ribs 14, 14 on opposite sides thereof which embrace the opposite sides of the member 10. At one end of the member 11 is a downwardly projecting car 15 adapted to project into one of the slots 13, 13.

A spring 16, formed preferably of wire, is

bent intermediate its ends to form a V the closed portion of said V being bent to form an eye 17 which is rigidly fastened to the member 11 by suitable means such as a rivet 18. The legs 19, 19 of the V-shaped spring 16 extend along the obverse face 20 of the member 11 from the rivet 18 toward the car 15 and are bent upwardly to form two loops 21, 21 constituting handles. Said legs extend forwardly from the handles 21 over and in contact with a bar or bridge 22 and then are bent to project downwardly through a hole 23 in said plate and terminate in two portions 24, 24 which are bent away from each other adjacent to the ear 15 and are adapted to project beneath the plate or member 10 at opposite ends of the slot 13 in which they are located, locking the car 15 within one of the slots 13 and preventing the same from being withdrawn from said slot or orifice and thus holding the two members 10 and 11 in interlocking engagement.

A projection 25, constituting a stop, is formed on the member 11 and projects between the legs 19, 19 of the V spring 16 adjacent to their free ends. The member 11 is provided with a slot 26 through which a strap may be passed to attach the member 11 to an overshoe or other article of apparel.

The operation of the device hereinbefore specifically described is as follows: Assuming the member 10 to be fastened by a strap extending through the slot 12 to an overshoe and the member 11 to be fastened by another strap extending through the slot 26 to said overshoe and it is desired to lock the two members 10 and 11 together, the user holds the member 10 with one hand and grasping the spring 16 by the handles 21, 21 presses said handles toward each other until the legs 19, 19 at their free ends abut against the stop 25. He then pushes the car 15 downwardly into one of the slots 13 and releases the spring, whereupon the free ends 24, 24 of said spring move away from each other and beneath the portion of the plate 10 adjacent to the opposite ends of the slot 13 in which said ear and said springs are located. It will be seen that when the parts are thus locked together the car 15 prevents the members from being moved laterally with relation to each other and that the two ends 24, 24 of the spring prevent the member 11 from being moved transversely away from the member 10. Thus the two parts are securely locked together.

The ribs 14, let on the member 11 assist in placing the member 11 upon the member 10 in alinement therewith and also assist in preventing the parts from rocking one upon the other and becoming displaced longitudinally with relation to each other.

Referring to Figs. 4 and 5 a modified form of my invention is illustrated which is particularly adapted to be fastened to heavy articles of apparel, such as overcoats, especially rubber coats and lumbermens coats. In these figures 10 is a cylindrical diskshaped member having an orifice 13 therein and a concave annular rim 27 surrounding said orifice. Said member 10 has a hole 28 in the bottom thereof whereby it may be attached to an article of clothing by means of a rivet extending through said hole. The member 11 is formed of sheet metal and is adapted to be fastened to said article of clothing by rivets which would extend through the holes 29, 29.

A V spring 16 is bent at its closed end to form an eye 17 which is fastened by a rivet 18 to the member 11. Said V-shaped spring has legs 19, 19 which extend toward the opposite end of said member 11 from that to which it is fastened by the rivet'18. Said legs are bent to form loops or handles 21, 21 and from said handles the legs extend forwardly and downwardly from the obverse to the reverse side of said member 11. and are bent outwardly away from each other, the ends 24: 2% thereof extending through holes 30, 30 formed in ears 15, 15 on said member 11.

A stop 25 is provided upon the member 11 and extends between the free ends of the legs 19, 19 so as to limit the distance to which either of said legs may be moved toward each other. The particular object of the stop 25 in this form of my invention as well as in the form illustrated in Figs. 1 to 3 inclusive is to make certain that both of the legs at their free ends shall be de- Copic: of this patent may be obtained for tached from the member 10 or 10, as the case may be, when the handles 21 or 21, respectively are moved toward each other, for if no stop of such a nature and location were present, all of'the bending might be done on one of the legs and then only one of the free ends 24 or at, as the case might be, would be detached from the member 10 or 10 i The operation of the device illustrated in Figs. 4 and 5 is very similar to that illustrated in Figs. 1 to 3. In connecting the parts together in interlocking engagement, the handles21, 21 are pressed toward each other, moving the free ends 2%, 2% toward each other until the extreme ends thereof 7 pass within the holes 30. The user then inserts the ear 15" in the orifice 13 and releases the handles 21, whereupon the free ends of the spring move apart and project into the interior of the concave rim 27. The device is then looked against lateral movement in any direction except one, by the ears 15 and said parts are locked together in that direction by the free ends 2%, 24: projecting into the interior of'the concave rim 27.

Having thus described my invention, what I claim and desireby Letters Patent to se cure is:

A clasp buckle having, in combination, two members formed of sheet metal adapted to interlock one with the other and a spring bent intermediate its ends to form two legs, said spring rigidly fastened intermediate its ends to one of said members, the free-ends of the legs of said spring adapted to engage the other of said members and hold said members in interlocking engagement and a stop on said first-named member located between the legs of said spring.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

WILLIAM P. BARTEL.
